3. Lathe Machine
Lathe is a machine, which removes the metal from a piece of work to the required shape &size

4. Component Description

5. Types of Lathe Engine Lathe
The most common form of lathe, motor driven and comes in large variety of sizes and shapes.
Bench Lathe
A bench top model usually of low power used to make precision machine small work pieces.
Tracer Lathe
a lathe that has the ability to follow a template to copy a shape or contour.

6. Automatic Lathe
A lathe in which the work piece is automatically fed and removed without use of an operator. Cutting operations are automatically controlled by a
sequencer of some form
Turret Lathe
lathe which have multiple tools mounted on turret either attached to the tailstock or the cross-slide, which allows for quick changes in tooling and cutting operations.
Computer Controlled Lathe
A highly automated lathe, where both cutting, loading, tool changing, and part unloading are automatically controlled by computer coding.

7. Engine lathe
An engine lathe is a horizontally shaped piece of machinery that is most often used to turn metal manually. By turning the metal and using special cutting tools the lathe is capable of forming the metal into specific shapes. As its name implies, it is often used to create metal pieces for use in an engine, whether it be for an automobile, a tractor, a boat, or any other motorized vehicle or machine.

8. Bench Lathe
A bench lathe is a material reduction machine built into a bench or worktable. A lathe takes a solid block of a material and reduces it to create a symmetrical item. Using a bench lathe, you can cut, knurl, drill, or sand material down to create a new object. The lathe is designed to hold the block at two points and spin it while allow the user to reduce the material to the new shape.

9. Tracer Lathe
The tool slide on a tracer lathe is guided by a sensitive, hydraulically actuated stylus that follows an accurate template. The template may be an accurate profile on a thin plate or a finish-turned part. Although tracing mechanisms generally are accessory units attached to engine lathes, some lathes are especially designed as automatic tracing lathes. Optional accessories for use on tracing...

10. Automatic lathe
Automatic lathe, or machine lathe, units are lathes that are fed commands from a computer or control panel and then work automatically. While these lathes can work on a variety of materials, they are primarily made to work with metal. The typical design for an automatic lathe includes six spindles, which allow the lathe to work on six pieces of metal at once. Common operations for a machine lathe include forming shapes and tools, and threading metal into screws and drill bits.

11. Turret lathes
Turret lathes are used for machining parts with complex shapes from bar stock or individual blanks. Screw machines are turret lathe equipped with a feeding and clamping mechanism for bar stock. Turret lathes for matching individual blanks are known as checking machines; they are equipped with a chuck having a manual or mechanized clamp.

12. Computer Numerical Controlled (CNC)
A computer numerical controlled (CNC) lathe is a machine that performs cutting operations on a generally cylindrical work piece by contacting a single point cutting tool to the surface of the rotating work piece. The CNC system employed in most lathes today enables a work piece of the desired profile to be produced without having to be continuously supervised by an operator.
